Should I Buy This Hawaii Home? A Public-Records Due-Diligence Checklist
Twelve checks any Hawaii buyer can run from a laptop before they spend a dollar on a formal inspection. Most of these are free if you know where to look. Skipping any one of them has cost real buyers six figures in our circle.
-
Pull the parcel record (TMK, acres, zoning, island)
Confirms what you're actually buying — sometimes the MLS listing's lot size or zoning is wrong by enough to change what you can build.

-
Check the lava zone (Big Island only)
LZ 1 and LZ 2 properties have insurance and lender constraints that can reset your monthly carrying cost by hundreds of dollars.

-
Check the FEMA flood zone
Coastal, valley, and stream-adjacent properties may be in AE, VE, or X flood zones. AE/VE require federal flood insurance for any federally-backed mortgage. Premiums range $400–$3,500/yr depending on elevation.

-
Pull recent permit history
What was permitted, what wasn't. Open or expired permits transfer with the property — meaning you inherit the obligation to close them out. Unpermitted additions can cost $20–60k to legalize retroactively.

-
Verify recent sales + ownership history
Frequent flips (sale within 1–3 years) are sometimes a flag for unaddressed issues. Owner-of-record matching the listing agent's claims matters for offer credibility.

-
Check shoreline setback (coastal properties)
Hawaii's shoreline setback rules limit construction within 40 ft of the high-tide line statewide, with stricter rules in some counties. Existing structures inside the setback can sometimes be repaired but not rebuilt or expanded.

-
Look up archaeology / cultural-site overlays
Coastal sites, mauka ridge sites, and certain valley parcels overlap recorded burial or cultural sites. Discovery during construction triggers SHPD review and can halt projects for weeks or months.

-
Verify utility status (cesspool / septic / sewer)
Hawaii's 2050 cesspool conversion mandate means a cesspool-served property will eventually need $25–55k of conversion work. The buyer's bank may or may not require the conversion at closing.

-
Run termite inspection history
Prior tent fumigation history is a useful signal. No history at all on a 50+ year old Honolulu home is a flag — either the inspections weren't done or the records weren't preserved.

-
Check leasehold vs fee simple
Some older Honolulu condos and parts of plantation-era Big Island sit on leasehold land. Confirm fee simple status from the deed before offer.

-
Pull the assessment + tax-bill history
Assessed value vs market price tells you about potential property-tax reset on transfer. Hawaii has no state-level Prop 13 cap, so high assessed-value step-ups are real.

-
Spot-check neighbor activity
Active permits within 500 ft (especially demolition or large additions) can mean construction-noise impact for years. Pre-MLS listings nearby can signal a neighborhood turnover that may help or hurt your timing.

Run a Property Brief →What this checklist won't tell you
Public records are necessary but not sufficient. The hands-on checks that public records can't replace:
- Real termite inspection — boots-in-the-dirt probing of accessible framing.
- Roof condition — public records show permit history; only a roof inspector tells you what the next 5 years look like.
- Plumbing + electrical health — the stuff behind walls. A dedicated plumbing scope camera + electrical panel inspection beats any record search.
- Drainage — what happens when 4 inches of rain falls in 90 minutes (which it does, every couple of years). Walk the property in heavy rain if you can; otherwise look for stains and erosion patterns.
- Neighbor relations — public records won't capture "the guy uphill blasts EDM at 2 AM."
Run public records first to filter out the deal-breakers cheaply. Spend on inspections only on the homes that pass the public-records pass.
